Difference between V1 and V2


To find the percentage difference between two numbers, we first need to calculate the absolute difference between them. In this case, the absolute difference between 155 and 128 is 27.

Next, we need to find the average of the two numbers. The average of 155 and 128 is (155+128)/2 = 141.5.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 155 and 128 is (27/141.5) x 100 = 19.12%.

This means that the second number (128) is 19.12% less than the first number (155).
